ion: relates to an automatic poseimen'tioned, which can be readily applie'd to-fan ordinary phonogra h without the form of a coile ich isadapted for was larger phonogra h,

for the motor mechanism (not shown) and the frame 2 forthe phonographmechanism,

the mainshaftfi, the cylinder 4, thefeed-nut' 5, the back-rod" 6, thespeaker-arm 7 its lift-lever 8, the reproducer 9 and the recordcylinder10 mounted on .the main cylinder, are of thefwell known character andform employed" "in phonographs of this type, and

do not constitute any part of the present invention. The longcontrolling-lever 1 1 is pivoted at apoint intermediateits ends to theconnecting-bracket 12 having the flat foot 13 thereon, by means. ofwhich the stop mechanism is referablyattached tothe honograph. hisal-z'tachment is made by oosening the screws 14 employed for'fasteni-ngthe phonogra h-frame to the case, thenslipping the foot 0 theconnecting-bracket under the I base-plate 15 of theirame, after whichthe screws 14 are tightened, thus clam ing thef0ot 13 of theconnecting-bracket etween the base-plate of the frame and the cover 16of the case and securely and rigidly holdingthe stop mechanism in properposition.- In

this type of phonograph the free end of the 'starting lever 17 protrudesu ward. through the slot 18 in the base-plate o the frame, and the motormechanism is adapted to be started by moving theend of this leveroutward,- that istoward the adjacent end of the frame, and to'be stoppedby moving the end of this lever inward toward the middle portion of theframe. The actuating-end 19 of the con trolling-lever is located back ofthe startinglever and 'on its forward ed e are provided the'recess 20and the shoul er 21, in which recess and against which shoulder'thestarting-leveris adaptedtorest' and to be held when in its open oroperative position.

The actuating-spring 22 is preferably. in

c spring with the hook 23 on its outer end adapted to engage thestarting-lever and the eye 24 on its inner endby which it is connectedwith the controllinglever, as by means of the rivet 25. The bend 26 ispreferably provided near the actuating end of the controlling-lever tobring the respective parts thereof in the ro er plane, and theactuating-spring is, pre era 1y passed through the aperture 27 inthisbend. It is evident that the tension ofthe actuating spring isslightly diagonal, so that the actuating end of the controlling-lever isdrawn forward at the same time the starting-lever is drawn inward, andthe starting-lever is thus securely held in the angle of the shoulder inthe front edge of the controlling-lever.

The trip-bracket 28 'is preferably formed of a flat plate adapted torest and slide endwise on the upper side of the trip end of the controllinglever, with the ears 29 and 30 formed from the body of the plateand bent downward over the front and back edges of thecont-rolling-lever. The flattened or leaf spring 31 is attachedto thebracket, as by means of the rivet-pin 32 passed through the apertures as33 in the ears thereof and through the tubular aperture 34 formed in thespring, and the handle 35 is preferably provided on the front end of therivet-pin. The leaf-spring 31 is adapted to press against the under sideof the stop-lever, so that the tripbracket 'can be readily adjusted byfm'cefullysliding it longitudinally along the lever and is then held inany desired position by the frictional contact of the spring.

The rear portion'SG of the trip-bracket extends under and to the rear ofthe elevated track-bar 37, as the same is formed in this type ofphonograph, along which track bar the foot 38 of the speaker-arm isadapted to travel. The indicating finger 39 is formed or attached on therear end of the tripbracket, and extends upward behind the track-bar andin front of the record-cyliinler, and the point it) of this finger isadapted to be adjusted by a proper movement of the tripbracket toregister with the end of the indentations on the record-cylinder, or toany other point with reference to which it is desired to stop the motormechanism.

For use in the larger phonograph the triplever 41 is preferably formedof strong, stiff wire, and is pivoted to the trip-bracket at apointbehind the track-bar, whence it extends forward and preferablyoutward to an angle or bend, as at 42, normally directly under thetrack-bar, whence it extends directly forward in the path of thedepending lift-lever S of the speaker-arm and is doubled upward andbackward upon itself, as at 43,

to the upwardly extending end or shoulder H'wlnch normally abuts againstthe forward face of the track-bar; The trip-lever thus descrilmd is thepreferred form when made of wire, but it is evident that this particularconstruction is not essential for the performance of its properfunctions, so long as the lever is provided with an arm, as 43, in the)ath of the lift-lever and a cant-acting shou der, as 44, in abutmentwith the face of the phonograph frame, which arm and shoulder areeccentric to the axis of the pivot of the lever. for the purposes ofthis invention, the liftarm need not be distinguished from thespeakenarm to which it is pivoted, for they And it will be understoodthat,-

both travel together and it is immaterial whether the trip-lever is inthe path of the one or the other.

In use, when the starting-lever is thrown toward the end of thephonograph into position. for starting the motor mechanism, theactuating end of the cont-rollinglever is drawn forward by the action ofthe actuating-spring, so that the starting lever is enaged in the recessand against the shoulder formed in the front edge of thecontrollinglever, and it is likewise held in this position ,while themotor mechanism operates the phonograph mechanism and the re )roducer ismoved from the inner towards the outer end of the record-cylinder. Whenthe depending lift-leyer 8 comes in contactwith the arm 43 of thetrip-lever, the same is carried outward, and in so doing the shoulder-14 of the trip-lever, being in abutment with the forward face of thetrack-bar, slides along the same and becomes a movable fulcrum, aboutwhich fulcrum the trip-lever is rotated and its pivot is carriedor'thrown forward. This forward movement of the pivot of the trip-leverthrows the trip-bracket with the trip-end of the controlling-leverforward and the actuating-end of the controlling-lever backward, so thatthe shoulder in the frontedge thereof is moved laterally out ofengagement with the starting-lever. and the actuating-spring then pullsthe starting-lever inward and stops the motor mechanism.

The parts of the stop mechanism are so proportioned and positioned thatby adjusting the point of the indicating-finger to register with theouter end of the indentations on the recort'l-cylinder the motormechanism will bestopped when the buttoinarm (not shown) of thereproducer has traveled to the same end of the indentations. It isevident that when the starting-lever is again thrown outward to .theposition for starting the motor mechanism, thestop mechanism will beautomatically set for another action as before.

Referring to the smaller phonograph illustrated in Sheet 2 of thedrawings, the short control]ing-lever 11 is pivotedintermediate its endsto the connecting-bracket 12 having the foot 13*, which foot is adaptedto be clamped between the base-plate 15 of the phonograph-frame and thecover 16 of the motor mechanism as described above for the largerphonograph. The actuating-end 19 of the short controlling-leyer islikewise locatedback of the free end of, the startingleverl'i of themotor mechanism ant, l is provided with the recess 20 311th'tll'sllotlltlcl 21 which are adapted to receive and stop" thestarting-lever 17 when the same is thrown outward to the position forstarting the motor mechanism.

' The ordinary actuating-spring 22 is pro vided with the hook. 23adapted to engage 2o r 46, and at theother endto the springqpost' 47which is formed or attached on the-speed adjusting-lever '48 the motormechanism-- asaiso the. startingeleverfand the eye 24 in the otherend-adapted to-eonneet with the short 545.1" The. actuating-spring 22"therein on the remote" side of its pivot post preferably tensienTof-ithe. sprin put the actuatingend-" of the controllingdever slightlyforward "when the startingdever inward; 1t.

I I

f 4When'the alternate actuating-spring 22" is employed, the" ordinary"actuating-spring 22! can lie-omitted in the stop mechanism for thesmaller hono'graphs without-affecting the essentia operations of thesame; for,; when using the short controlling-lever, the

'sprir'ig' between the free end of the startinglever andthecontrollingdever is'not'so im-' portant because of thecomparatively-short distance between the sto -shoulder 21"? of thecontrolling-lever an thereof.- When the ordinary actuating spring is notused; the operator readilys'ets t e stop mechanism for action, by usingthe forefinger ofthe left hand for moving'the actuating end of thecontrollin -leve r'-forward :at the same time the thumb b the same handis "used for 'r 'noving the starting-lever ontf' Shard.

Y The track-bar the smaller phonograph is formed integral with thebaselate '15 of the-phonograph-frame 2 throng out .its lengthys'o; that-there is no s ace under- *neath the track bar through whlchthetrip-vbracket "and trip -'lever" can extend.
